I use an iPod that I havnt updated from iOS 6. Also works on Android.
Mmm… Try a blank SD card or a flash drive to see if you can access them.
The software is pritty straight forward (RAV file hub without +).
My file hub and my device are on the bottom of screen.Select my file hub .this should give you your connected stuff. Once into folders Manage was used and ^back.
Maybe try connecting OP-1 w/shift&com after or before software, if not already.
At least the software isn’t complaining you need file hub connected to work. Can you view photos if you select My Device?
